  2. 1. Elastic properties and phase stability of shape memory alloys from first-principles theory

    Author : Chun-Mei Li; Levente Vitos; Denis Music; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction materials; Konstruktionsmaterial;

    Abstract : Ni-Mn-Ga and In-Tl are two examples of shape memory alloys. Their shape memory effect is controlled by the martensitic transformation from the high temperature cubic phase to the low temperature tetragonal phase. Experimentally, it was found that the martensitic transformation, related to the elastic properties, is highly composition-dependent. READ MORE
